Used these every day for a week leading up to a fireman’s ball, and they definitely worked! Only reason it’s a 4 star and not a 5 is because even when I left them on for 20 minutes instead of 30 there was a slight irritation/pain to my teeth for a few hours afterwords, but nothing unbearable.

[This review was collected as part of a promotion.] I’ve been using crest whitening strips for years! I wasn’t aware of the multiple options they have available with different levels of whitening (until now!). I have sensitive teeth naturally, and I try to stay on top of keeping my teeth bright and shiny - a dental freak if you will. Crest has been the one and only brand that gives me consistency, does not compromise my teeth sensitivity, and has others complimenting on my teeth. Literally nothing else compares. I’ve tried so many! I was so excited to see these pop up on my screen.

To be honest, i've never really believed in all the products out there. I gave 3d crest a try... and O M G! im in day 7 right now and the results are already amazing!! Can't wait for the end result.. This really works great, they are shining white! thx

The Crest 3D whitening kit is a must have for anyone who is dedicated to their teeth and oral care and wants their smile to look absolutely stunning. If you are looking to enhance your beautiful smile, look no further than this incredible product that will do just that and more

Love this kit and would recommend using it. I would be careful if you have sensitive teeth though. It doesn't turn white right away, but you do see results slowly if you continue to use it consistently for a couple of weeks or months. I'm always afraid of swallowing the bubbles or chemicals that spill out of the tape. You're not supposed to brush the teeth after peeling it. I normally brush and then put them on for 30 minutes, take it off and go to sleep. 

I love the white strips honestly !!!! It is the best product I have ever tried ! i use to have braces so when i got them taken off i had a lot of patches on my teeth but this product has done miracles ! now my whole family uses them ! If my dog could use them i would make him !

This product worked really well for me. The pros were that I definitely noticed my teeth getting White, but the only downside is that I have sensitive teeth and I felt my teeth get more sensitive after using this. I would use this product again just without daily use.

I’ve only used this set once, mostly due to the high price. While it does whiten your teeth pretty well for being something you can get at the store, it did make my gums hurt/burn when the strips were on. This discomfort is not awful, but it seems like there are other ways to whiten teeth. For the price it does it’s job, but be warned about the burning.

[This review was collected as part of a promotion.] Impressive Results in Just One Week! These Crest Whitestrips are super effective my teeth looked visibly whiter after a few uses. They’re easy to apply, comfortable to wear, and stay in place. I had mild sensitivity, but it didn’t last long. Each strip is individually packaged, which makes it convenient and hygienic. For the results you get, the value is definitely worth it!

The only thing that’s gotten my teeth to whiten these past few years! It saves you so much money from going to an actual teeth whitening place, and you see effective results within a few days to week. I try to do these every 2-3 days, and get another box for maintenance every 6 months.
